Some of the master sites have gone and some have changed the directory tree, new sites have also been added.
The master sites have been updated, so that the 1.6.8 version is
fetchable, allthough this patch will make the current version 1.6.5
also fetchable, because the "askapache" site provides all versions.
The "askapache" site does not provide any publicly readable files,
at the URL http://wireshark.askapache.com/download/src/, only the
"Parent Directory" and "all-versions" directories are available.
I'll submit another PR of net/wireshark update from 1.6.5 to 1.6.8.
How-To-Repeat: cd ports/net/wireshark
make fetch
